% based on jcse.cls revised 4/20/07 by Heejong Lee, Seoul National University
% adapted to JIDM 04/15/2010 by Mirella Moro, Universidade Federal de Minas Gerais
% current version: 18.January.2012

% Following instructions are also modified from acmtrans2m.cls:
%
%  -> \documentclass{jidm}
%  -> \markboth{}{}
%         takes 2 arguments and it is for the left- and right-page headers:
%         the first set of braces is assigned for author's name(s)
%         and
%         the second set of braces is assigned for the title
%             (if the title is too long, contraction may be needed
%  -> \title{}
%         if the title is too long, it can be separated by \\
%  -> \author{}
%         author1 \\ author1 affiliation
%         \and
%         author2 \\ author2 affiliation
%  -> \begin{abstract}
%  -> \end{abstract}
%
%  -> \category{}{}{}
%         takes 3 arguments for the Computing Reviews Classification Scheme.
%         ex: \category{D.3.3}{Programming Languages}{Language Constructs and
%                   Features}[data types and structures]
%                   the last argument, in square brackets, is optional.
%  -> \terms{} (ex: \terms{Human Factors, Languages})
%  -> \keywords{} (in alphabetical order \keywords{document processing, sequences,
%                      string searching, subsequences, substrings})
%  -> \begin{document}
%
%  -> \begin{bottomstuff}
%          similar to \thanks
%          for authors' addresses; research/grant statements
%  -> \end{bottomstuff}
%  -> \maketitle
%
%     Now you can start the body of the paper; your figures, tables and
%          use all the latex constructs.
%
%  -> \begin{acks}
%          acknowledgements
%  -> \end{acks}
%
%  -> \bibliographystyle{jidm}
%  -> \bibliography{mybib_file}
%
%     ****
%     If your paper has been accepted with a separate (electronic only)
%        appendix, you need to add the following control sequence:
%
%
%       body of appendix
%!!!!!! \appendixhead has be cut into two: \appendixhead and \elecappendix
%!!!!!! See end of file. (jtb)
%
%  -> \end{document}
%
% Do not worry about the other definitions in this style file
% Remember to compile: latex, bibtex, latex latex
%
% Bibliographic cite forms needed:
%
%  \cite{key}
%    which produces citations with author list and year.
%    eg. [Brown 1978; Jarke, et al. 1985]
%  \citeA{key}
%    which produces citations with only the author list.
%    eg. [Brown; Jarke, et al.]
%  \citeN{key}
%    which produces citations with the author list and year, but
%    can be used as nouns in a sentence; no brackets appear around
%    the author names, but only around the year.
%      eg. Shneiderman [1978] states that......
%    \citeN should only be used for a single citation.
%    \citeNN{refkey1,refkey2} for author [ref1year; ref2year]
%    \citeyear{key}
%        which produces the year information only, within brackets.
%
% Abbreviated author lists use the ``et al.'' construct.
%
% The above are examples of required JIDM bibliographic cite formats needed.
% *******************
% Here is the complete list of cite forms from the chicago bibliographic style
%
%  \cite{key}
%    which produces citations with abbreviated author list and year.
%  \citeNP{key}
%    which produces citations with abbreviated author list and year.
%  \citeA{key}
%    which produces only the abbreviated author list.
%  \citeANP{key}
%    which produces only the abbreviated author list.
%  \citeN{key}
%    which produces the abbreviated author list and year, with only the
%    year in parentheses. Use with only one citation.
%  \citeyear{key}
%    which produces the year information only, within parentheses.
%  \citeyearNP{key}
%    which produces the year information only.
%
% Abbreviated author lists use the ``et al.'' construct.
%
% `NP' means `no parentheses'

% this file: Modification of chicago.sty for new JIDM bibliography
% style, which is similar (but not identical) to the ``Chicago'' style.
%
% chicago.sty: Style file for use with bibtex style chicago.bst, for
% bibliographies formatted according to the 13th Edition of the Chicago
% Manual of Style.
%
% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
% with lots of tweaking to make it look like APA style, along with tips
% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
% newapa.sty formed the basis of this style, chicago.sty. Author-date
% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
% supports annotations.
%
% Version 4 (August, 1992):
% - fixed chicago.bst and chicagoa.bst to handle long author lists in
%   sorting
% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
%   ``article'' entries are handled correctly
% - modified chicago.sty to format entries with 2nd and subsequent lines
%   indented.
%
%   Citation format: (author-last-name year)
%             (author-last-name and author-last-name year)
%             (author-last-name et al. year)
%             (author-last-name)
%             author-last-name
%             author-last-name (year)
%             (author-last-name and author-last-name)
%             (author-last-name et al.)
%             (year) or (year,year)
%             year or year,year
%
%   Reference list ordering: alphabetical by author or whatever passes
%    for author in the absence of one.
%
% This BibTeX style has support for abbreviated author lists and for
%    year-only citations.  This is done by having the citations
%    actually look like
%
%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
%
% The LaTeX style has to have the following (or similar)
%
%     \let\@internalcite\cite
%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
